Operating Temperature Range
No visible defect, and dimensions are
within specified range.
The capacitor should be visually inspected for evidence of
defect. Dimensions should be measured with slide calipers.

Appearance and Dimensions
Marking
To be easily legible
The capacitor should be visually inspected.
The capacitor should not be damaged when DC voltage of
200% of the rated voltage (DC1 to 3.15kV) or DC voltage of
250% of the rated voltage (DC500V) is applied between the
lead wires for 1 to 5 sec.

Wires
No failure
(Charge/Discharge currentV50mA)
The capacitor is placed in the container with
metal balls of diameter 1mm so that each
lead wire, short circuited, is kept about 2mm
off the metal balls as shown in the figure at
right, and AC1250V(r.m.s.) <50/60Hz> is
applied for 1 to 5 sec. between capacitor
lead wires and metal balls.

As shown in the figure at right, fix the body of
the capacitor and apply a tensile weight
gradually to each lead wire in the radial
direction of the capacitor up to 10N (5N for
lead diameter 0.5mm), and keep it for 10±1
sec.

Lead wire should not be cut off.
Capacitor should not be broken.

Strength of Lead
Each lead wire should be subjected to 5N (2.5N for lead
diameter 0.5mm) of weight and bent 90° at the point of egress,
in one direction, then returned to its original position and bent
90° in the opposite direction at the rate of one bend in 2 to 3
sec.
Bending
Appearance
No marked defect
The capacitor should be firmly soldered to the supporting lead
wire and vibrated at a frequency range of 10 to 55Hz, 1.5mm in
total amplitude, with about a 1-minute rate of vibration change
from 10Hz to 55Hz and back to 10Hz. Apply for a total of 6 hrs.,
2 hrs. each in 3 mutually perpendicular directions.

The lead wire of a capacitor should be dipped into a ethanol
solution of 25wt% rosin and then into molten solder for 2±0.5
sec. In both cases the depth of dipping is up to about 1.5 to
2mm from the root of lead wires.
Temp. of solder: Lead Free Solder (Sn-3Ag-0.5Cu) 245±5°C
H63 Eutectic Solder 235±5°C
Lead wire should be soldered with
uniform coating on the axial direction
over 3/4 of the circumferential direction.
